Professor Qian has come to RMIT from The University of Queensland in 2013 where he was the Reader in Materials Engineering, School of Mechanical and Mining Engineering.Currently Professor Qian also holds the appointments of Honorary Professor of The University of Queensland, Australia, and Specially Appointed Professor of Osaka University, Japan.
Professor Qian's major academic outputs include:
- Light Alloys: Metallurgy of Light Metals, 544 pages, 5th edition, Elsevier, 2017 (I. Polmear, D. H. StJohn, J. F. Nie and M. Qian),
- Three other Elsevier books as co-editor: Titanium Powder Metallurgy: Science, Technology and Applications, 648 pages, Elsevier, 2015 (M. Qian and F. H.

- 280 peer-reviewed journal articles as of Feb 2022 (355 in Scopus including book chapters, conference papers and editorial notes)
- One commercialised invention - a technology for magnesium alloys (WO03062492; EP1466038; US20050161121; CN1639389A; DE60330309D1).
His publications have attracted more 13,500 Scopus citations (> 12,400 citations excluding self-citations of all authors) with an h-index of 54 as of January 2022.
He and his team have recently developed an ultrasound assisted metal 3D printing process ("Grain structure control during metal 3D printing by high-intensity ultrasound", Nature Communications, 2020, 11, 142, which can convert the long columnar grains into fine equiaxed grains, demonstrated on Ti-6Al-4V and Inconel 625. In addition, it allows for the fabrication of gradient materials by switching on and off the ultrasound during metal 3D printing. The audience reach within three weeks of the publication of this work through a RMIT news release was 146 million.
More recently, he and his team have developed a robust bulk micro-nano hierarchical copper material possessing exceptional bactericidal efficacy (Biomaterials, 2022, 280, 121721). This new copper surface can eliminate golden staph in 2 minutes, 120 times than a normal copper surface. The audience reach within three weeks of the publication of this work through a RMIT news release was 276 million.
He co-developed the widely accepted Interdependence Theory of Solidification (Acta Materialia, 2011, 59, 4907-4921; 2010, 58, 3262-3270) and the in-situ phase transformation controlled selective laser melting (SLM) process for 3D printing of titanium alloys (Acta Materialia, 2015, 85, 74-84).
His other fundamental contributions include those that focused on heterogeneous nucleation (Acta Materialia, 2007, 55, 943-953; 2006, 54, 2241-2252, J. Chem. Phys. 2009, 130, 214709, J. Crystal Growth, 2012, 355, 73-77), powder metallurgy of titanium alloys (Acta Materialia , 2014, 68, 196–206) and aluminium alloys (Acta Materialia, 2010, 58, 5667-5674), de-alloying and re-alloying (Acta Materialia, 2019, 168, 376-392; Electrochimica Acta 2015, 164, 288-296) and thermodynamics of materials (Acta Materialia, 1998, 46,1669-1681; Acta Metallurgica et Materialia, 1994, 42, 4083-4086; 1994, 42, 4087-4091; Metall Mater Trans A, 2002, 33A, pp. 1285-1287; 2000, 31A, 2659-2661).
Professor Qian is an elected Fellow of American Society for Metals International (FASM), the World's foremost professional society for materials scientists, engineers and technicians (established in 1913). He currently serves as an Associate Editor for both Acta Materialia and Scripta Materialia and is on the editorial board for a number of other journals. In addition, he is the Series Editor of Elsevier on Additive Manufacturing and an Advisory Editor of Elsevier on Advanced Manufacturing and Materials. Also, he serves as the Publications Committee Chair of Materials Australia.
Professor Qian has received nine research awards including the American Society for Metals (ASM) 2006 Henry Howe Marion Medal with his colleagues, TMS Light Metals 2003 - Magnesium Technology Award, the inaugural Australian CAST-CRC Industry Partners Award (2003) and RMIT Engineering 2019 Executive Dean's Research Excellence Award - Level E (professorial level).
Professor Qian initiated the first biennial international conference on Powder Metallurgy Titanium (PM Ti) in 2011 in Australia, which has been Successively held in New Zealand (2013), Germany (2015), China (2017) and the United States (2019). It has become a premier conference on PM Ti and the scope of this conference was extended to cover 3D printing of titanium alloys since the 2015 conference in Germany. In addition, he served as the Organising Committee Chair for the first (2017) and second (2019) Asia-Pacific International Conference on Additive Manufacturing (APICAM) organised by Materials Australia in Melbourne at RMIT University.
